A kind of pepper seed germination accelerating method
Technical field
The present invention relates to vegetable growing field, be specifically related to a kind of pepper seed germination accelerating method.
Background technology
A lot of vegetable seeds need vernalization, and the general seed that needs vernalization can be divided into two classes: a class is that fruit vegetables seed sprouting is slow, need to urge kind, as tomato, capsicum, eggplant, cucumber; An other class is that summer temp is high, causes germination rate of vegetable seeds low, thus also need to urge kind, as asparagus lettuce, spinach, capsicum, garlic.Different vegetables, vernalization mode difference separately.Hang well method, refrigeration, mix micromicrofarad etc.Different vernalization modes, corresponding different vegetable seeds.Before general vernalization,, first through seed selection, sterilization, seed soaking, finally be only vernalization.Conventional germination accelerating method can improve percentage of seedgermination, shortens germination time, alleviates Field diseases, and seedling seedling is neat, Miao Zhuan.But existing germination accelerating method does not all have to improve the nutrient component of vegetables, further improve the quality of vegetables.
Summary of the invention
The invention provides a kind of pepper seed germination accelerating method, this germination accelerating method can not only improve percentage of seedgermination, shortens germination time,, without weeds, grows after seedling replanting fast in seedbed, well developed root system, and the yield and quality of capsicum is high.
The technical solution used in the present invention is:
A kind of pepper seed germination accelerating method, is characterized in that, comprises the following steps:
(1) prior to seeding seed was shone after 1-2 days, select the seed of full seed, the seed of select is put in container, in chilly water, soak 5-6 hour; Then drop into the 10-15 minute that soaks seed in seed soaking agent, pull out cleanly, wherein seed soaking agent is formulated by following component, the percentage by weight of each component is: lactofen 30-40ppm, brassin lactones 10-15ppm, gibberellin 1-3ppm, DA-6 10-15 PPm, potassium nitrate 40-50ppm, alga fertilizer 200-300ppm, malic acid 10-15 ppm, ferrous sulfate 0.2-0.4%, surplus is water, mixes after each component is dissolved in respectively to water, be diluted with water to desired concn, stir and get final product;
(2) seed soaking is dipped in the container that fills nutrient solution again, container is put into 600w microwave equipment, the firepower microwave treatment with 60% 10 seconds-20 seconds, then stops microwave treatment, pulls out;
(3) clean with clear water again;
(4) above-mentioned soaked seed is bound up with gauze, squeeze and remove part moisture, put into refrigerator at 0-5 DEG C of refrigeration 10-12 hour, taking-up is put into 25-30 DEG C of warm water and is soaked 12 hours, pulls out, again put into refrigerator and cooled and hide 8-10 hour, taking-up is reentered in the warm water of 20-25 DEG C soaks 8-10 hour, then pulls out with bundle and and put into presprouting of seeds case, at 20-30 DEG C, constant temperature vernalization 12-24 hour, takes out;
(5) seed after constant temperature vernalization is being mixed thoroughly with rare earth, and concrete grammar, for after 2-3g rare earth is joined stirring in 40-50g water, adds 2-3kg seed, fully mix thoroughly, then seed and fine earth are mixed thoroughly by the weight ratio of 1:3, are seeded into according to a conventional method in seedbed,, within 3-4 days, germinate.
Nutrient liquid described in step (2) is formulated by following component; every liter of nutrient solution comprises the component of following weight: ferrous sulfate 0.3-0.5g, ammonium molybdate 0.2-0.3g, zinc sulphate 0.01-0.03g, manganese sulphate 0.01-0.03g, cupric sulfate pentahydrate 0.2~0.4g, vitamin B1 0.02-0.03g, vitamin c 1-2g, taurine 0.3-0.5g, vitamin D 2-5mg, vitamin E 0.4-0.7g, ferrous sulfate 2-4g, surplus is water.
In seed soaking agent of the present invention and nutrient liquid, water insoluble active ingredient can adopt water soluble preparation to be added to the water dissolving again.
beneficial effect
Germination accelerating method of the present invention, improve the germination rate of pepper seed, germination rate can reach 100%, improve the field Anti-temperature difference changing capability of capsicum, in seed soaking agent, add brassin lactones, promote growth of seedling, all have obvious facilitation and seedbed to generate, increased output and improved Quality of Capsicum without weeds to capsicum root system and plant height.Germination rate can improve 6-12%, and germinating to seedling rate reaches more than 95%.Germination period can shift to an earlier date 1-2 days.
Embodiment
A kind of pepper seed germination accelerating method, comprises the following steps:
(1) prior to seeding seed was shone after 1-2 days, select the seed of full seed, the seed of select is put in container, in chilly water, soak 5-6 hour; Then drop into the 10-15 minute that soaks seed in seed soaking agent, pull out cleanly, wherein seed soaking agent is formulated by following component, the percentage by weight of each component is: lactofen 35ppm, brassin lactones 14ppm, gibberellin 2ppm, DA-6 13 PPm, potassium nitrate 45ppm, alga fertilizer 250ppm, malic acid 13 ppm, ferrous sulfate 0.3%, surplus is water, mixes after each component is dissolved in respectively to water, be diluted with water to desired concn, stir and get final product;
(2) seed soaking is dipped in the container that fills nutrient solution again, container is put into 600w microwave equipment, the firepower microwave treatment with 60% 10 seconds-20 seconds, then stops microwave treatment, pulls out;
(3) clean with clear water again;
(4) above-mentioned soaked seed is bound up with gauze, squeeze and remove part moisture, put into refrigerator at 0-5 DEG C of refrigeration 10-12 hour, taking-up is put into 25-30 DEG C of warm water and is soaked 12 hours, pulls out, again put into refrigerator and cooled and hide 8-10 hour, taking-up is reentered in the warm water of 20-25 DEG C soaks 8-10 hour, then pulls out with bundle and and put into presprouting of seeds case, at 20-30 DEG C, constant temperature vernalization 12-24 hour, takes out;
(5) seed after constant temperature vernalization is being mixed thoroughly with rare earth, and concrete grammar, for after 3g nitric acid rare earth is joined stirring in 40g water, adds 3kg seed, fully mix thoroughly, then seed and fine earth are mixed thoroughly by the weight ratio of 1:3, are seeded into according to a conventional method in seedbed,, within 3-4 days, germinate.
Wherein, nutrient liquid is formulated by following component; every liter of nutrient solution comprises the component of following weight: ferrous sulfate 0.3-0.5g, ammonium molybdate 0.2-0.3g, zinc sulphate 0.01-0.03g, manganese sulphate 0.01-0.03g, cupric sulfate pentahydrate 0.2~0.4g, vitamin B1 0.02-0.03g, vitamin c 1-2g, taurine 0.3-0.5g, vitamin D 2-5mg, vitamin E 0.4-0.7g, ferrous sulfate 2-4g, surplus is water.
